These flooded areas combine fresh and salt water, creating a unique ecosystem where the diverse flora attracts a wide variety of fauna. The lagoons, known as pateiras, were reopened in the 1980s and have become a refuge for numerous water birds, including the ducks of the Aveiro estuary, from which they are named.

The entire narrow peninsula separating the lagoon from the ocean is formed by a sand bank deposited off the prehistoric coastline that eventually closed in and filled with water. It is hugged by a wide road with a good shoulder for biking, all the way from the Sao Jacinto ferryboat dock at the southern tip, to Ovar in the north, with two small beach towns in between, worth a detour. To keep it straight, this section highlights the longest part, from the southern tip to Torreira. The middle section goes from Torreira to the bridge that crosses the lagoon to th east, and the norther section goes from the bridge to Ovar, where the peninsula ends. The Ria (lagoon) continues as a natural canal parallel to the coast for another 50 kilometer or so to the north.

The coastal bike route (EuroVelo1) follows a long stretch of the canal formed by the occlusion of the rivers restricted from flowing directly into the ocean by the sand build up along the shore, eventually forming the large Aveiro lagoon, where the rivers finally break through to the ocean.

On the lagoon side of the road the local fishermen continue to attach their traditional small shallow boats and also fish with rods from the wooden piers. On the other side a trailhead with picnic tables and restroom is a good rest area with a quick trail to a marshy pond in the nature reserve promising great birding opportunities.
